|•||Quantity name: If you click on a selected quantity in the tree, you can edit the name.|
|•||Description: Enter a description of the quantity.|
|•||Variable name: This name is used for display purposes. For example if one of the variables of a port p has the quantity length it will be denoted as p.x.|
|•||SI Symbol: Enter the official SI-symbol here. Enter combinations as nominator/denominator (e.g. Electric Resistance: kg.m2/A2.s3)|
|•||Units: Every quantity can be expressed in several unique units (i.e. a unit can be assigned to one quantity only). You can enter new units here or edit existing units that belong to the selected quantity.|
|•||Unit Symbol: For display purposes every unit has a specific symbol. It is shown here in a read-only field.|
A quantity can have an alias name. Enter this alias as a subentry of the main quantity. This alias name refers to the main quantity and therefore to the same associated units.
